Coming back to this game and needing to read up on the changes since; this post has been helpful in deciding on both to keep playing my Wizard and in how to play him since Blizzard/Hydra.

That is interesting. Coming back from when? May 2012? There were about 5 major patches since the last update of the OP (August 2012)... not to say the info is outdated, but obviously lots of stuff just wasn't around in August. The game changed a lot since then.
